Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I think the Soundstation is not initializing properly. Try this:
Try removing the batteries if any, and unplugging the device from power and other connections, and leaving it on a (dry, non-humid, non-dusty) shelf for overnight. Then put the batteries back in and try the device again.
Given that all those operations simply 'failed', I think that your Polycom phone most likely has a serious electronics operating or control defect that would require repair.
How old is the Polycom phone station in question?
